Should PSG bid, and then pay, the 222 million euros needed to prise Neymar from the Catalan capital, they would struggle to meet UEFA's financial fair play conditions that limit a team to losses of no more than 30 million euros over a three-year cycle.

And that is despite a mega-money sponsorship deal with the Qatar tourism board.

According to Tebas, "no-one believes" the commercial revenue figures presented by PSG to justify their spending.

"PSG cannot have figures in which PSG's commercial rights exceed those of Real Madrid and Barcelona," said Tebas.
